Abstract: PURPOSE: To achieve stable power supply by detecting from the transient region the power tide current due to disregulation fault occurred in the return power transmissinn system and further by transmitting the load power quantity from a central power transmission station as the command corresponding to a load limiter characteristice of power station.  
     CONSTITUTION: Power PS at the transmission end of the power transmision system led to a load 23 through a main transformer 22 from a power generator 21 and power P r  at the receiving end thereof are detected by detectors 32 and 31, differential power Δ P between them is derived by a deviation arithematic device 33 and the vibration of the power is applied to comparators 34 and 34. On the other hand, the phase Q 3  of the power at the transmission end is detected by a power phase deviation arithmetic device 25 to supply it to comparators 28 and 27 as in case of the power. In such the constitution, the sampling amount detected as stated above is applied to a computer 38 preset and relay drivers 36, 37, 29 and 30 to decide whether the system is put in the disregulating condition or not and to watch the disregulation fault

Abstract: PURPOSE:To always execute read-out at a high speed by always storing a record whose use frequency is high, in a resident area, and directly reading out a necessary data from the resident area, in case of reading it out. CONSTITUTION:When a work program reads out a necessary record, for instance, records R32, R51 and R71, a key of an aggregation 23 of records being in a resident area on a main storage device 2 is retrieved by a copy 24 of a key directory. As for the record R71, its corresponding key K71 exists, and the record R71 is read out of the aggregation 23 of recordes stored in the record resident area on the device 2 and it is delivered. On the other hand, in case of the records R32, R51, their corresponding keys K32, K51 do not exist, therefore, whether they exist in an aggregation 21 of records being a buffer area on the device or not is decided as usual. In case of the record R32, it exists, therefore, the record R32 is fetched from the aggregation 21, and the corresponding use time T2 of a buffer management table 22 is udpated. The record R51 dose not exist, therefore, it is transferred to a buffer of the oldest use time on the device 2, and R51 is fetched from the aggregation 21 and delivered.

Filed: 1978-09-11
Abstract: PURPOSE:To omit the luminance adjustment even with application to the areas of different transmission distances as well as to increase the S/N ratio by using the bipolar ternary signal for the self-clock signal and also inserting the differentiating circuit to the reception side. CONSTITUTION:Data signal (a) and clock signal (b) are applied to transmission circuit 11 to obtain the bipolar ternary signal. With this ternary signal luminous element 14 is modulated to be sent out to optical transmission line 15. At the reception side, the optical signals are applied to differentiating circuit 18 and fault detection circuit 24 via photoelectric conversion circuit 16 and amplifier circuit 17. In other words, input d and d' of circuit 18 are turned to differential output e and e' to be applied to detection circuit 19.

Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To ensure high quality high definition recording by minimizing relative positional shift between a recording medium and an ink sheet thereby eliminating disturbance at the time of transferring a coloring agent to the recording medium. SOLUTION: An ink sheet 22 having a coloring agent layer is placed between a recording medium 23 and a thermal recording head 21 and the coloring agent is transferred from the ink sheet to the recording medium by heating the thermal recording head. In such a thermal transfer recorder, the thermal recording head, the ink sheet, the recording medium and a platen roller 30 have widths wider than a recording region R.

Title: Method and device for selecting data storage medium to be demounted by automatic storage library
Inventor: JIYOZEFU CHIYAARUZU HARUTOUNGU
IPC: G11B27/34
Filed: 1991-04-18
Abstract: PURPOSE: To previously demount a storage medium when occupied peripheral storage devices are left under inactive state for a relatively long prescribed time in an automatic storage library under idle. CONSTITUTION: When the peripheral storage devices in which the storage medium is mounted are under inactive state, the storage medium is demounted in order to respond to a mount requirement under holding. Also, even though a requirement under holding is not made, when all peripheral storage devices are occupied and moreover one or plural devices like that are left under inactive state for a relatively short prescribed time, the storage medium is demounted in order to produce unoccupied peripheral storage devices. Further, regardless of the existance of mount requirement under holding or the occupied state of the peripheral storage device, the storage medium within respective occupied peripheral storage devices, which are left under inactive state for a relatively long prescribed time, is demounted and transfered to a storage cell within the storage library.  By this way, resources of peripheral storage devices under inactive state are not continued to use for a long period of idle with the library.

Title: Manufacturing of semiconductor element
Inventor: TATEFURU NOBORU
IPC: H01L29/72
Filed: 1978-09-14
Abstract: PURPOSE: To improve accuracy of measurement by annealing a wafer, which is standing on a fixture being used in an emitter layer forming process, at a low temperature in an inert gas containing H 2 , and by exposing a surface for inspection.  
     CONSTITUTION: After an opening is made in an oxidized film on a N type Si base board 1, a P-type base is diffused, and then the opening is covered with PSG 5. An emitter 6 is formed by heat treating the board in a mixed atmosphere of N 2  and O 2 . Then PSG is etched away after the wafer standing on a fixture is kept for 20 minutes at 470C in H 2  0.2l/min. and N 2  1.3l/min.. At the same time, a pair of emitter and base electrodes are formed to a test element provided on a section of the wafer. With this constitution the emitter surface is protected by PSG during the low temperature annealing; therefore, contamination is prevented until the emitter-base junction process, and scratches are reduced because a number of wafer handlings is reduced. Thus a stable relation in a measured hFE right after the diffusion and after an Al electrode is formed, is obtained.

Abstract: PURPOSE:To attain stable pickup by providing a means detecting the vibration of a camera, means correcting the vibration and a means applying drive control to the correction means so as to form a closed loop frequency characteristic to be a notch filter type. CONSTITUTION:A movement detector 103 detects the movement of a picture of a television camera 102 to drive a variable apex angle prism 101 via a control unit 106 and an actuator 107. The tilt of the optical axis of the prism 101 is controlled by packing a silicon group liquid between two parallel galas plates and varying the angle between the parallel glass plates thereby correcting the movement of the picture due to a blur of a camera. Taking the vibration frequency due to a hand blurring given to a camera concentrated in a range of 0.1-3Hz into account in general, the center frequency of a BPF 104 in the unit 106 is selected to be 0.5-2.0Hz, a high frequency cut-off frequency to be 3Hz or over and a low cut-off frequency to be 0.5Hz. Thus, an output picture stable at all times against the blurring of the camera is obtained.

Abstract: PURPOSE:To avoid such a case where data are not collected due to a setting mistake of a clock frequency by using a transient recorder TR to set again the clock frequency at a level where sampling is possible in case the level of the first clock frequency is too high. CONSTITUTION:A CPG (clock pulse generator) clock frequency information collecting means 15 reads the clock frequency of a CPG5 and sets it to a file 17. While a TR channel number information collecting means 14 reads the channel number of a TR 6 and sets it to a file 16. Then a deciding means 19 decides said channel number and the maximum sample frequency with which the TR 6 can perform a sampling action and sets them to a file 20. A comparing means 21 compares the obtained CPG clock frequency with the maximum sample frequency of the TR. Then the TR maximum sample frequency is extracted out of the file 20 when the CPG clock frequency is equal to or larger than the maximum sample frequency and then sets the extracted frequency to the CPG5. At the same time,the CPG clock frequency of a data collection information file 23 is rewritten to the reset value.
